_____________________________________
 
(1)The expected life of SARs granted under the stock-based compensation plans is based on historical vested stock option and SAR exercise and post-vest forfeiture patterns and includes an estimate of the expected term for stock options and SARs that were fully vested and outstanding.
(2)The risk-free interest rate is based on the U.S. Treasury yield for a term consistent with the expected life of SARs in effect at the time of grant.
(3)The Company estimates the volatility of its common stock at the date of grant based on the historical volatility of the Company's common stock for a period equivalent to the expected life of the SARs, which it believes is representative of the expected volatility over the expected life of the SARs.
(4)The Company expects to continue paying quarterly dividends at the same rate as the three months ending on July 31, 2013.
